The lights in each room of the dormitory building are turned on one after another.

In the middle of the night, who is there crying wolf?

Lin Xiaoxiao put down her phone, got out of bed, opened the dormitory door, and poked her head out to look out.

At the end of the hallway, several people stood at the door of room 612.

It was the three people who lived in room 612: Zhang Yi, Yang Jiajia, and Sun Ting, but Li Ping was not among them.

Lin Xiaoxiao had just delivered them hometown specialties at noon, and three of the four people in the dormitory were sick, and now that it was evening, what happened?

Lin Xiaoxiao had a bad premonition and walked out of the dormitory door with her coat on.

Room 612 doorway.

Lin Xiaoxiao asked, "What's going on?" Why are you standing at the door?"

Zhang Yi's hair was messy, her eyes were red and swollen, and she looked frightened, pointing to the dormitory and her voice trembled, "Li Ping...... Li Ping is dead!"

Dead?!

In room 612, the lights were bright, and Li Ping was lying on the bed, the head of the bed and the floor were covered with blood.

Lin Xiaoxiao walked into the room with the courage to find that Li Ping's face was covered with blood, her eyes were wide open, and she stretched out her hand to test her nose, without a trace of breath.

Critically ill patients often can't detect their snort, and Lin Xiaoxiao touched her carotid artery again, but there was no pulse.

Sure enough, he was dead.

And Li Ping's body temperature began to cool, and it was presumed that he had been dead for a while.

Lin Xiaoxiao tried to stabilize his mind, exited the room, and dialed 110.

Ten minutes later, the police went to investigate the scene.

A cordon was put up at the door of dormitory 612.

Some police questioned the students in the dormitory on the sixth floor, and the roommates of the deceased Li Ping and Lin Xiaoxiao were the key targets of investigation.

After making the record, Lin Xiaoxiao was about to go back to the dormitory to rest, and vaguely heard someone in the police whispering, "Ruling out homicide, it is suspected that he died of illness, and the specific cause should be further autopsied." Also, the three roommates of the deceased in the same dormitory all had a fever and fell ill, and it is recommended to notify the CDC ......"

Lin Xiaoxiao pricked up her ears and stayed outside the cordon, wanting to hear more news.

The police began to chase people away, "Don't watch, go back and rest." ”

Back in the dormitory, Lin Xiaoxiao opened the glass window and looked downstairs.

The lights of the police car flashed, Li Ping's body was taken away, and the three girls in the same dormitory were also taken away by the 120 ambulance.

It was already two o'clock in the morning after this toss.

was frightened, and Lin Xiaoxiao and her roommates couldn't sleep.

The four people in the dormitory held a dormitory meeting again, but the content of this dormitory conversation was not the usual parents and gossip stars, but Li Ping from the 612 dormitory this time.

Boss: "Although Li Ping is usually a bit second, her popularity is quite good, so there shouldn't be anyone looking for revenge and killing her, right?"

Lingling: "Is it to kill for money?"

Lianzi: "We are all poor students, where do we get the wealth for people to plot?"

Lin Xiaoxiao: "I heard the police say just now that he seems to have died of illness. ”

"Sick to death?" Boss Qi turned over from the bed and sat up, staring at the position of Lin Xiaoxiao's bed, "How could it be that he died of illness?" Although Li Ping is usually a little sloppy, she is very strong. ”

Lingling: "When I went to the cafeteria to eat yesterday, I happened to meet Li Ping, and she was complaining about headaches, eye pain, and back pain. I just don't know what disease progresses so fast? It only takes two days to kill a living person. ”

Lianzi remembered one thing, "At noon, Xiao Xingguo found a mouse in Li Ping's dormitory, could it be related to mice?"

"Plague?!"

The four of them spoke in unison.

The four people in the dormitory are all students majoring in preventive medicine, and they talk about infectious diseases.

Lin Xiaoxiao was the first to express a different opinion, "The plague is also called the 'Black Death', if it is the plague, the patient will be purple and black due to lack of oxygen. I have seen Li Ping's appearance after her death, although there are symptoms of bleeding, but there are no symptoms of bruising all over the body. ”

Boss Qi: "There are too many types of infectious diseases related to rats, plague, epidemic hemorrhagic fever, leptospirosis, endemic typhus...... There are more than 30 species to count. ”

"It's epidemic hemorrhagic fever!" Lin Xiaoxiao suddenly spoke, in a rather certain tone.

"Why? Do you know any other clues?" asked Boss Qi.

"Well, at noon, I sent food to Li Ping's dormitory, and found that Li Ping's face, neck, upper chest and eyes were red, she reported a fever, Lingling also said that she met Li Ping yesterday complaining of headache, eye pain, and back pain, and all the symptoms were combined: fever, three reds, three pains, ......"

Before the words were finished, the other three roommates said in unison, "Epidemic hemorrhagic fever!"

Fever, redness, and pain are typical symptoms of epidemic hemorrhagic fever.

The knowledge from books is applied to reality, and the roommates are a little excited.

Lingling: "Boss, should we tell the police the news?"

Boss Qi was hesitating, and Lin Xiaoxiao said: "No, the police should know that it is an infectious disease, and it has been reported to the CDC." ”

After chatting for a while, the roommates became very sleepy and fell asleep one after another.

Lin Xiaoxiao took out his mobile phone and found that Angel Xiaobai was still online.

It's already 3 o'clock in the morning, and this guy hasn't slept yet?

Lin Xiaoxiao sent a message, "It's almost dawn, haven't you slept yet?"

After a while, there was no response.

Could it be that Xiaobai's family has an accident again?

Lin Xiaoxiao remembered the scene of meeting Angel Xiaobai on the Internet.

Three years ago, Lin Xiaoxiao participated in the volunteer activities of the autism group and added a group on the Internet, and there was a netizen named Angel Xiaobai in the group, who is a family member of an autistic person.

The two met on the Internet at that time, although they did not meet in reality, but the two chatted very well on the Internet and added friends to each other, and this chat was more than three years.

Xiaobai has an older brother with autism, his parents died many years ago, and Xiaobai has been taking care of his brother for several years.

My brother's symptoms are good and bad, Xiaobai takes care of his brother while working, and it is inevitable that when he is exhausted, whenever he encounters his brother's illness, Xiaobai will chat with Xiaolinzi on the Internet.

Xiaobai was in a depressed mood, and Xiaolinzi came to enlighten him.

When Xiaobai is in a good mood, he will also share good things with Xiaolinzi.

After a long time, Xiaobai called Xiaolinzi Miss Tree Cave.

Xiao Linzi also said that Xiaobai is his brother's angel.

When my brother was sick before, Xiaobai would also send a message to Miss Xiaolinzi in the middle of the night, and now he is online again, but there is no response, is it my brother's illness again?

Lin Xiaoxiao sent another message over, "Are you accompanying your brother?"

Soon there was news back.

"No, it's working overtime. ”

What kind of work? 3 a.m. overtime?

Immediately afterwards, there was a message from Angel Xiaobai, "Why didn't you sleep?"

Xiao Linzi: "Something happened in the dormitory building, and I'm busy until now, but my roommates are asleep now." ”

Angel Xiaobai: "It's not good for girls to stay up late, you should rest early, I'm busy here, let's talk next time." ”

Angel Xiaobai's avatar on the phone is dim, and he is offline.
